STORM-WINDOW FASTEN ER.

SPECIFICATION forming part of Letters Patent No. 443,348, dated December23, 1890.

Application filed October 25,1889. Serial ii 328,210. (Nomodeh) To allwhom iv may concern:

Be it known that I, ABRAM P. ANDREWS, of Dover, in the county ofStraiford and State of New Hampshire, have invented certain 5 new anduseful Improvements in Storm-Vindow Fasteners; and Ido hereby declarethat the following is a full, clear, and exact description of theinvention, which will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to letters of reference -marked thereon,which form a part of this specification.

My invention relates to improvemel'its in storm-window fasteners.

It is designed to take the place of the com mon screws now in use.

It gives a firmer grip and requires no screwholes in the windowframe.

In the drawings herewith accompanying and making apart of thisapplication, Figure 1 is a View of my improved fastener. Fig. 2 is asection of a window and frame, showing method of applying my improvedfastener, and same letters refer to like parts.

In said drawings, a represents the outside or storm window; Z), theoutside casing-strip; 'L', the jamb; j, the lower window, and 7c thebead between the upper and lower windows.

The storm-window sash has holes therein at suitable distances apart forthe fasteners to pass through.

The fastener has a long body or shank c, 011 one end of which is athread g, adapted to 3 5 receive a thumb-nut d, and on the other end alug e to grip the outside casing, as shown in Fig. 2. is flattened andextends out at the side beyond the line of said shank, thus forming a 40projection f, which gives a broad base to rest against the casing and toprevent the fastener from turning when being tightened by saidthumb-nut.

To apply myimproved fastener, first insert the fastener in the outsidewindow sash from the inside, with the lug turned in, as shown by dottedlines in Fig. 2, place the window in position, turn fastener half round,and apply thumb-nut until the lug grips against the casing-strip, asshown in Fig. 2. The flat projection f, pressing against the edge of thecasing, prevents the fastener from turning and the lug from losing itsgrip while the thumb-nut is being tightened.

The end of the shank 'near the lug To remove the window, first loosenthe nut, then force the fastener inward until the projection f is beyondthe casing-strip, and turn the fastener until the lug is in the positionindicated by dotted lines in Fig. 2. The projection should be on thatside which will prevent the fastener from turning when the nut is beingtightened. The fastener will turn readily when the nut is loosenedwithout pressing inward, there being no projection on the opposite sideto prevent it. Unless the fasteners could be turned round to theposition shown in dotted lines the lugs would notpass by thecasing-strip.

The fasteners being once inserted in the window-sash, it will beunnecessary to remove them again, and they may be put away with thewindow, and thus be always ready for use. IVhere the upper sash comesdirectly against the casing-strip b, a recess may be made in said stripsufficiently deep to receive the lug and allow it to turn therein.

The advantages of my improved fastener consist in the ease with which itmay be applied, the greater tightening-power, and consequently closerjoint than can be secured by means of a screw, and in the avoidance ofthe necessity for the unsightly screw-holes in the window-casing, whichnot only disfigure the window, but also, by reason of the said holesrotting out during the warm weather in summer, render new holesnecessary every time the window is put on.

Having thus described my invention and its use, what I claim, and desireto secure by Letters Patent of the United States, is-

The combination, with a storm-\vi ndow having holes in the sash, of aseries of fasteners adapted to pass through said holes, each fastenerhaving on one end a lug adapted to grip the windowcasing and on theother a thread and thumb-nut, and having a shank straight on one sideand with a fiat projection on the other, substantially as and for thepurposes set forth.

In testimony that I claim. the foregoing as 10o my own I affix mysignature, in presence of two witnesses, this 14th day of October, A I).1889.

ABRAM I. ANDRElVS.
